microPIMS

microPIMS is a wireless, non-intrusive ultrasonic corrosion/erosion monitoring system developed by Sensor Networks, Inc. It consists of battery-powered sensors that take thickness measurements at user-defined intervals and transmit the data wirelessly to a receiver/gateway. The system operates using long-range (>1 mile/1.6km) sub-gigahertz wireless connectivity.

Each microPIMS sensor is designed to be attached to the outside of pipes or vessels using magnetic or clamp-style attachments, without needing to penetrate the asset's surface. The sensors employ ultrasonic transducers to measure the wall thickness from the outside, enabling corrosion/erosion rate monitoring without process interruption or hot work permitting.

The transmitted data is received by the gateway and uploaded to webPIMS, a cloud-based or on-premises web portal software for analysis, trending, and data management. The webPIMS software allows users to monitor multiple sensors simultaneously, track corrosion rates over time, and receive alerts if preset thresholds are exceeded.

The microPIMS system is intrinsically safe, making it suitable for use in hazardous areas. It is designed to provide frequent and reliable corrosion data without the need for manual inspections, reducing costs associated with scaffolding, insulation removal, and personnel exposure in harsh environments.
